//! Issue #101: the `tish:tty` capability (raw mode, terminal size, key/resize events) is
//! available on every backend behind the `tty` feature. CI has no real terminal, so this
//! asserts the module loads and degrades gracefully (size → null, isTTY → a boolean, the
//! event/raw-mode primitives are functions). Interactive behavior is covered manually.

use std::path::PathBuf;
use std::process::Command;

const EXPECTED: &str = "\
isTTY: boolean
size: null
setRawMode: function
read: function
readLine: function
alt: function function
";

    let tish = PathBuf::from(env!("CARGO_BIN_EXE_tish"));
    let out = Command::new(&tish)
        .args(["run", "--backend", backend, "--feature", "tty", fixture])
        .output()
        .expect("spawn tish run");
    assert!(
